[gmx-users] multidir, Segmentation fault

Hi,

I ran two equilibration simulations to generate two production tpr with 
different velocities.
mdrun_mpi runs fine with each tpr (no explosion, the systems are stable).
However, if I set the multidir option, I get segmentation fault.
My system: Debian Buster, GROMACS 2018.6

Thanks for your suggestions,
Tamas
